Features:

Have you been wanting to get more sound out of your existing Invidia Q300, R400 Gemini or N1 exhaust? Look no further and swap your axleback section to a Nameless Performance Muffler Delete. Upgrading the axleback section of your existing exhaust gives you the best of both worlds, providing you the benefit of now having two optional sound levels for your vehicle which can be swapped out with relative ease. The exhaust tips of this muffler delete are 3.5 inches in diameter with a polished stainless steel finish.

Featuring bolt-up factory fit flanges and hangers, as well as manufactured in Woodland, Washington, USA, at Nameless Performance they take pride in the details of their exhaust systems and invest the best into what we build for our customers:

• Exhaust Tip Color: Polished 
• Exhaust Tip Style: Single Wall
• Exhaust Tips Size: 3.5″ inch
• Quad exit
• CNC Mandrel Bent Tubing
• 100% T304 Stainless Steel Construction
• Precision fabricated and fitted welding
• Hand TIG welded
• Solid hanger bars
• Laser-cut flanges
• Staggered arrangement exit
• Includes the necessary hardware for the installation

A simple modification like the replacement of the back muffler box on a car can transform the day to day driving experience for the owner of the vehicle, and this exhaust is no different. We love to claim that the first and foremost benefit to our exhaust systems are that they sound incredible and really make driving more enjoyable. Baffled/chambered mufflers are an amazing invention of science, with the ability to cancel specific frequencies of sound to provide a near silent operation. For those of us who are enthusiasts, however, mufflers and resonators that are designed like the factory ones are provide us with zero feedback. Switching to a muffler delete promotes more tone across the powerband and a free flow exhaust design.

Beyond the sound signature and improvement in powerband, the most noticeable difference in the addition of our exhaust is the weight savings of 25 pounds! The replacement of a packed and baffled muffler with a straight section of tubing or straight through muffler design generally nets 8-12ft lb on the STI and 6-8ft lb on the WRX.

Installation

Installation is a snap with basic hand tools. Removal of the factory exhaust requires removing four bolts and four exhaust hanger bushings from the Q300 / R400 / N1 muffler. Each side of our axleback exhaust system is then hung from the factory exhaust hanger bushings and bolted to the Q300 / N1 / R400 Gemini midpipe. We provide upgraded nuts, bolts and replacement gaskets that are used when re-installing the upgraded exhaust, as well as a pair of three hole urethane exhaust hanger bushings. Hold the tips centered in the cutout in the bumper and tighten the nuts to ~20ft lb with hand tools.
